 Static file serving middleware.

## Installation

```js
$ npm install koa-send
```

## Options

 - `maxage` Browser cache max-age in milliseconds. defaults to 0
 - `hidden` Allow transfer of hidden files. defaults to false
 - `root` Root directory to restrict file access
 - `gzip` Try to serve the gzipped version of a file automatically when `gzip` is supported by a client and if the requested file with `.gz` extension exists. defaults to true.
 - `format` If true, format the path to serve static file servers and not require a trailing slash for directories, so that you can do both `/directory` and `/directory/`

## Root path

  Note that `root` is required, defaults to `''` and will be resolved,
  removing the leading `/` to make the path relative and this
  path must not contain "..", protecting developers from
  concatenating user input. If you plan on serving files based on
  user input supply a `root` directory from which to serve from.

  For example to serve files from `./public`:

```js
app.use(function *(){
  yield send(this, this.path, { root: __dirname + '/public' });
})
```

  To serve developer specified files:

```js
app.use(function *(){
  yield send(this, 'path/to/my.js');
})
```

## Example

```js
var send = require('koa-send');
var koa = require('koa');
var app = koa();

// $ GET /package.json
// $ GET /

app.use(function *(){
  if ('/' == this.path) return this.body = 'Try GET /package.json';
  yield send(this, __dirname + '/package.json');
})

app.listen(3000);
console.log('listening on port 3000');
```
